Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to use a UMG throbber?

Can someone explain the general way throbber works? Say, I have a C++ loop that utilize callable UFUNCTION to spawn actors. That's a heavy task and main game thread freezes until all actors are spawned. How can I keep throbber spinning if game thread is hanging? Should I spawn actors on tick to prevent game hanging, or is there any multi threaded UMG loading widgets to give spawning function all power?
